Appendix A: Radio images of the cluster fields

The radio images of the clusters up to the virial radius are presented here. Natural weights were used to make these images.

A1576: GMRT 610 MHz (left) and 235 MHz (right) images in contours. Positive contours are black, and negative ones are grey in all the images in Appendix A. The contours are at 0.3 × (± 1,2,4,...) mJy beam-1 at 610 MHz and 2.0 × (± 1,2,4,...) mJy beam-1 at 235 MHz. The HPBWs at 610 and 235 MHz are 8.1′′ × 6.7′′, p a 53.2° and 24.6′′ × 17.8′′, p a 43.8°, respectively. The 1σ levels in the 610 and 235 MHz images are 0.08 and 0.55 mJy beam-1, respectively. The circle has a radius equal to the virial radius for this cluster (9.70′).
